![]() This problem can be overcome first by cleaning the block. The above conditions cause overheating especially during city driving or parades. This lesser volume of coolant coupled with infrequent radiator flushes and coolant changes created an accumulation of solid rust around the rear cylinders of the block. The results were a lesser volume of coolant being pumped through the engine. When this spacer was installed the water pump impeller did not fill the extra one inch gap created by the water pump spacer. When the same engine was used in a Thunderbird it was necessary to install a 1&1/8″ spacer between the water pump and mounting cavity to accommodate belt alignments. This combination worked fine in the passenger cars and trucks. The water pump impeller was approximately ½” thick. The cavity for the water pump impeller was approximately 5/8″ deep. The timing cover for both the passenger car and Thunderbird were similar in design, both were built to accommodate the same water pump. The water pump for the Thunderbirds was the same as used on passenger cars and trucks. The T’Bird engines were the same engines used in thousands of Ford passenger cars and trucks, but the passenger cars and trucks did not have the same tendency to overheat. Also, there is a basic design flaw in the water pump system. The small tight engine compartment did not allow for free air flow to carry out the hot air transferred from the radiator. The primary reason for higher than normal operating temperature under these conditions was due to the design of the engine compartment. Even when new, under certain driving conditions (parades & city driving) when coupled with excessive ambient temperature, the Thunderbirds were prone to run toward the hot side of normal. For your next steering repair, O'Reilly Auto Parts offers a selection of replacement steering gear boxes, pitman arms, tie rods, and more to help you complete your repair and get back on the road safely.When it comes to the7 Thunderbirds, this subject more than likely, has been discussed and written about more than any other. If you notice any of these symptoms, the steering gear box may need to be replaced or rebuilt to restore the steering system to proper functionality. This can make it difficult to control the vehicle, and may also cause grinding noises, burning oil smells, or power steering fluid leaks. Over time, the gears and bearings inside the steering gear box can wear out, causing looseness or play in the steering. In manual systems, the driver provides all the force needed to turn the wheels, and in power-assisted systems, the driver is assisted by hydraulic power from the power steering pump while turning the wheels. The steering gear box on your vehicle may be manual or power-assisted, depending on the design of your car. Input from the steering wheel and steering column turns a gear inside the steering gear box that moves the pitman arm pressed onto the output shaft gear, and the pitman arm may have to be removed and installed on a replacement gearbox if necessary. The steering box can be found on the driver's side of the vehicle, attached to the frame and connected to the steering linkage. The steering gear box is responsible for translating the rotation of the steering wheel through the steering linkage into wheel movement to turn the vehicle.
